For this reason," "the game will tell you what key to press. You don't need to use a keyboard " "on Android, though. You can get the menu with all common actions by pressing 'MENU' on the " "screen; some actions can be also done with hardware buttons " "(for example, CALL to get/use). " "Yes/no questions are answered 'yes' by touching the top of the " "screen, and 'no' by touching the bottom.\n" "You will learn some basics of Hydra Slaying in this tutorial.\n" "Note that Hydra Slayer is a puzzle roguelike. Maybe you prefer " "to figure out the basic rules yourself? If so, go back to the " "stairs and touch MENU then 'get/use' to exit the tutorial.\n", #else "Welcome to Hydra Slayer!\n" "You will learn some basics of Hydra Slaying in this tutorial.\n" "Note that Hydra Slayer is a puzzle roguelike. Maybe you prefer " "to figure out the basic rules yourself? If so, go back to the " "stairs and press 'g' to exit the tutorial.\n" "Note: for convenience, this tutorial tells you how to do things by " "using keyboard. You can also do them by pressing mouse: just move " "the mouse to the bottom right corner, and you will see icons " "to do all the most important actions (other than movement and weapon " "switching, which are done by clicking the map and the weapon list, " "respectively).\n" "If you feel lost, you can press '?' or F1 to get some Help.\n" #ifdef NOTEYE "Press Ctrl+M to change system options (audiovisual etc.).\n" #endif "Press Enter to close this message, and proceed " "to the next scroll to read it.\n", #endif "There are some mushrooms before you. Mushrooms block your way, so " "you have to cut them before you proceed. They also have many uses, " "though. They block the way of Hydras, and also provide additional " "\"heads\" which are useful with some of the special abilities, or " "for testing your weapons.\n" "However, the one before you simply blocks your way. You can cut it " "simply by moving into it. Make sure that you have selected your dagger " "as a weapon (press '1' or click it on the list" #ifdef ANDROID ", you can also use volume up/down buttons if you have them" #endif ").\n" "One thing about movement. You can move with " #ifdef ANDROID "hard buttons, touching the screen, " #endif "arrow keys, numpad, " #ifdef NOTEYE "mouse, " #endif "or with so-called \"vi keys\" (around J on qwerty). In this tutorial, the map is composed " "out of squares, and you can move in four directions. But for a real " "game, you can also choose 8-directional movement (allow diagonal movements " "for both you and hydras), or to have a map made of hexagonal cells. " , "There is a hydra before you! Not a big deal, since it only has one head. " "It will be as simple to kill it as to cut a mushroom. Again, make sure that " "the dagger is selected, and you will kill it simply by moving into it.\n", "The next hydra has two heads. Note that you see the list of all hydras you " "see on your screen. When you select the dagger, you will see \"x2\" next " "to the hydra; this means that it grows two heads for each head you cut. " "So your dagger will cut one head and the hydra will regrow two, which is " "not helpful.\n" "You can also switch to your machete by pressing '2' or by clicking it " "on the list. The hydra would regrow one head (+1), but it does not matter " "(if you cut all its heads, the hydra is dead and does not regrow). Thus, " "select the machete, and you will be able to kill it easily.", "There is a four-headed hydra before you! If you check both your weapons, " "you will see that there is no way to kill this one. You will need to " "find a better weapon. Thanks to the mushrooms which block the hydra, you " "can try to explore the room to the North.\n", "There is a shortsword before you, and it is just what you need! It is able " "to cut four heads at once, so you will be able to slay that four-headed " "hydra easily.\n" "Select your machete, go to the shortsword, and press 'g' to get it. " "You are currently only able to carry two weapons, one in each hand, " "so you will have to drop your machete. But the shortsword is better.", "There is a three-headed hydra before you! And it will be a problem. " "Hydra slaying weapons have magical enchantments which allow them to cut " "several heads at once, but there is a cost: it is impossible to attack a " "hydra which has less heads. So your shortsword will be useless, for now. " "You can attack with your machete, but the hydra will now have more than " "4 heads after it. If you think about it, you will see that it is impossible " "to kill it with your current weapons: it will always have an odd number " "of heads, and more than 1.\n" "Luckily you started with some tools to help with difficult cases. Your " "Powder of Stunning is able to stun all the heads of a single hydra completely. " "A stunned hydra cannot move or attack, but it would still regrow heads " "after an attack. However, you also have a Powder of Decapitation. It makes " "all the stunned heads disappear (and kill the Hydra if all the heads were " "stunned). Use the two powders in a combination, and the path will be clear!\n\n" "Press 'i' to see your inventory. To use the powder against the hydra, " "move next to it, press 'i', and select the powder to use it.\n", "The hydra before you might look difficult with its 9 heads. It regrows " "1 head after each attack with your shortsword, so it will have 3 heads " "after two attacks. However, it is still possible to defeat it with your " "current weapons (and without using powders). " "Find how to do this yourself! This is one of the two " "main challenges of Hydra Slayer: finding the combination of attacks " "which kills the given Hydra most effectively.\n" "Alternatively, you can also drink the Potion of Knowledge while the hydra " "is in your sight. It will show you the combination of attacks that it " "thinks is the best, and it will usually work correctly.\n", "Hopefully you now know the basics of Hydra slaying.\nIn the next chamber, " "there is a display of some items that are commonly used by Hydra slayers. " "You can pick up them and read what they do from your inventory ('i'). " "You can also press 'f'/'l' to get a list of all items, weapons, and hydras " "in your sight, and to get detailed information about each of them. " "Note that hydras will show the number of heads regrown when attacked by " "each of the 10 colors of blades.\n" "A hint: potions of Power Juice are very important! Drink them as soon as " "you find them, unless you really want a challenge.", "And the next chamber shows you some weapons. You will find the two most " "common kinds of weapons: blades (you already know these, they cut some " "heads and the hydra usually regrows some), and blunt weapons (these " "stun the hydra heads so they are unable to attack, but you will need " "to cut them with a blade to actually defeat them; on the good side, " "they are usually larger than blades, and will never cause hydras to " "grow more heads.\n", "There are more types of weapons available. The most successful slayers " "will be even able to find rare artifact weapons, with very special " "hydra slaying powers.\n" "But there is a general rule that the more powerful the weapon is, " "the less hydras it is able to affect. A shortsword cuts 4 heads, but " "it works only on " "hydras with at least 4 heads, and a Bisector takes half of the heads, " "but only if the number of heads is even.\nThe challenge is to find the " "set of weapons that makes you able to slay hydras as effectively as " "possible.", "There are stairs before you. They lead to the next level of the dungeon. " "Since your task is to slay all hydras, you can only use stairs if " "you have killed all the hydras on the current level.\n" "The stairs before you will take you into the beginning of the real game. " "Note that everything that you did in this tutorial does not count, " "and you will start with the usual set of items and weapons.\n" "Good luck, Hydra Slayer!", "Take care of your HP! Although it was possible to slay all the hydras " "so far without taking any wounds, it is not possible in general. You " "will lose HP when hydras attack you; you lose the game if it drops " "down to 0. On the other hand, successfully slaying a hydra will heal " "some of your HP, and also improve your maximum HP by 1. You do not " "regenerate HP automatically, so you will need to fight hydras (there " "are several other ways of healing, but they are very limited).\n" }; void generateTutorialLevel() { P.geometry = 4; P.race = R_HUMAN; setDirs(); vorpalRegenerate(); clearLevel(); topx = TBAR, topy = TBAR; for(int y=0; y': C.type = CT_STAIRDOWN; break; case 'r': C.type = rand() % 2 ?
